The rover’sdestruction left a massive void in scientists’ ability to study the hostile environment, and it’s not the first to have gone down. Itjoins a list of five deep-sea exploration vehicles that have been lost or near-fatally damaged on the job since 2003. They went AWOL all around the world—from the waters around Antarctica to just off a Japanese Island—for a host of reasons. Still, the secrets contained in the least hospitable parts of the ocean reveal why sending millions of dollars of machines after them is worth it."
